I just want to get over him

I can’t shake this..I’m trying to get over this guy. We were having casual sex for three months..we currently are still but I’ve come to realization that he isn’t into me like he was before or maybe this whole time it was a game..whatever the case I need to let this guy go. I don’t hook up with just anyone I actually really liked him we spend a lot of time together memories I don’t think I can ever forget I was treated horrible for 9 years with my ex and he came in and treated me right..we would go to eat..sit in the car and talk about things..drink milkshakes together and laugh and hook up and go on road trips..I know it’s nothing BIG but it was special to me because he’d always hold my hand and id always blush and he would always notice me smiling at him and smile back..♥️ I fell head over heels..and unfortunately in love with him. I have told him but it seems like once I did he kinda just lost interest I didn’t tell him I love him I told him I was falling hard. We even hung out when I was on my period..he’s spent over 100 dollars on motels just so we can be alone..even if it was just for a few hours and now I’m just getting a sense he’s not into it no more and instead of writing him a paragraph o ex more on how I feel and get a reply I won’t like I’m just gonna go my own little way..he doesn’t text me no more and doesn’t call me like he use to and he only texts me the day OF us hanging out to meet up and when I text him he says “don’t text I’m busy” so it’s like ok..that’s cool..than. It’s just so hard he’s all I think about. all day every day..I know I’ll be ok but I just want to be ok already..feel like he’s my soul tie
